Vacuum-Driven Surgical Suction and Irrigation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suction and irrigation systems in surgery require two separate energy sources, vacuum and irrigation, which is inefficient and inconvenient in an operating room setting.
Innovation Solution
A vacuum-assisted suction and irrigation system that utilizes a single energy source, where a suction and irrigation wand, connected to both a vacuum source and an irrigation fluid supply, employs a diaphragm-type fluid pump to deliver irrigation fluid under vacuum pressure, eliminating the need for separate power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate power sources (vacuum and electric pump) are used for suction and irrigation, then both functions can be provided, but device complexity and ease of operation are worsened
Solution Approach 1:
The patent combines the vacuum source and irrigation pump into a single integrated unit. The vacuum source creates negative pressure that draws irrigation fluid through a reservoir and delivers it through the surgical instrument, eliminating the need for separate electric pump and power source while maintaining both suction and irrigation functions
Solution Approach 2:
The vacuum source serves multiple functions simultaneously: it provides suction for removing fluids and debris, and it creates the pressure differential needed to pump irrigation fluid from the reservoir through the surgical instrument. This multi-functionality reduces the number of required components and power sources
2Adaptability or versatility
If two separate power sources are used, then both suction and irrigation can be provided, but ease of operation is worsened
Solution Approach 1:
The vacuum source and irrigation delivery system are merged into one unit, so the surgical instrument provides both suction and irrigation capabilities. The operator controls both functions through a single device rather than managing separate powered instruments, significantly improving ease of operation

AI summary
A vacuum assisted suction and irrigation system includes a suction and irrigation wand, an irrigation fluid supply, a vacuum source, and a fluid pump. The vacuum source is connected to a suction valve of the suction and irrigation wand to provide suction within the suction and irrigation wand. The irrigation fluid supply is connected to the suction and irrigation wand via the fluid pump to supply pressurized irrigation fluid to the suction and irrigation wand. The vacuum source is connected to the fluid pump to pressurize the irrigation fluid being delivered to the suction and irrigation wand.
